DAVID J. HAVENSTRITE oFnnwARK; NEVFJER Y l ICEFMAK INGAPhAI-IATUSLU No.42,1'Z7.

a, citizen of the United States; anda resident of Newark, in the countyof Essex and State of New Jersey, have invented certain new and usefulImprovements in Ice-Making Ap-'v peratus, of which the following isriffs];ecific i v tion.

for making plate-ice;- I Y Among its specific points of novelty is theproduction of-p lete-ice without the casingor cells that are genersllyused with the plateice lants. l

, ith thelfree zing-hlates heretofore thev refri erant, has "to produceits effect through t ewhole cake ofice, from one side thereof to theother;requiringthemonduction of the cold-producing agent through thetotel thi knees, With myinventiomthe ice is forme radially in alldirections, reducing the thickness through which the cold produoingagent has to act or befconduicted, saving thereby energy and time. Withplate plants heretofore used the freezing-surfaces have been nnremovsbleparts of the freezing-tank;

but with my invention the freezing-plates coils B snd'the latter areconnectedto' the-F. I vsix'ct' ion-piping; h of the pump H by means of 85" the pining b", top header G is connected -to'tne piping g, whichleadsto the mai'nhi'i'n'e '7 can he removed from the tank. l l

The invention is exemplifiedin the accom penying drawings, in whichvFi'nre 1 shows a sectional planfifviewof a buil ng with a plste'dceplant; 'Fi 2 represents a section of Fig. 1 on the line 'a: m.

Fig. is a partial axial section a elevation of one section of thefreezing-coils with their up urtenances. Fig;- i represents a sectionFigs.- 5 and 6- show enlarged fragmentary portions of Fig.

To use the invention, the tank 0, contain-' ing'the freezing-plates M,is filled with water. The compressor-engine D is started, exhausting theevaporated refrigerant, like ammonia,

from the brine'coohng tank G and discharg ing it into the condenser E,where it is condensed into a liquid by reason of first'ha'vi beencompressed in, the-compressor. an

then condensed to. a liquid by means of wa ter circulating through thecoil E with the watch-circulating flha'refrigerant isthen led into therinegc'ooling tank (1 by way of the piping g through the expansion-valveg, thereb 'foo'mpletin the c cle of therefri erantp rifle is circulated'of the brinecirculating pump H entering said pumpthrough the piping hand dischargi into the coil G bv way of the piping h, and t e said brineis cooled in the said tank by virtue of the expansion of the refri erantt ough the co' in the tank .G by means therein, as just described. Thecoole brine is led from the tank G through the piping g and enters themain brine-header I to cirou- -pipes n in the pipes N, enterstheleft-hand end of section 2, goes to the right-hand end of;secti0n 2,'.and passes down the vertical.

Each freezing-plate, with its ice frozenthereto, is raised out ofthe tank (1 by means of the cranes A? andcarried over the ice-sans W and out into sections by being loweredagainst the rails C to allow the saws to out the icetfrom the bottom tothe top thereof. 1316 freezin plate's, with the ice still adhering tbrought overv the openings B 1n the icehoiise'B and lowerd into thesame, the said ice-house beinglnaintgained at a low freezing talonpefature by means of coolingrcoilsB heQhsxtoperation is to thaw theVertical ipesi-Tl N N,&c., of the freezing-plates M fem the cakes ofice, and which is accomi p i hcd, by .couplin the hose R of thethawlnghpparatus with the end of the pipe M having the valve-chamber Land connecting the hose R withxthe end of the ipe having imember of thecouplingmt T e pump is [started and brine is drawn from the brinethawing-off tank It and circulated through a. fi'ezirigplate, the brinereturning to the said tank B. By reason of the brine in the tank R 5having been warmed thepipes of the freezing- Y plateare loosenedfrom-the ice surrounding- "them, and the said plate is next lifted outoi the ice-house by means of one of thecranes A and taken back to'becoupled iripos'ition 4fin the tank C, where it'is'again putinto eom-'mission; Thebrine in thetank R is kept warn1 ,bymeans of the exhaustofthe pump S, passing through the coil 8 in said tank.
